Abstract. The strength and stability properties of hierarchical load bearing networks and their strengthened variants have been discussed in recent work. Here, we study the avalanche time distributions on these load bearing networks. The avalanche time distributions of the V− lattice, a unique realization of the networks, show power-law behavior when tested with certain fractions of its trunk w...

We present solutions to statically load-balance scatter operations in parallel codes run on grids. Our load-balancing strategy is based on the modi cation of the data distributions used in scatter operations. We study the replacement of scatter operations with parameterized scatters, allowing custom distributions of data. The paper presents: 1) a general algorithm which nds an optimal distribut...

In Chile, office buildings are typically reinforced concrete (RC) structures whose lateral load-resisting system comprises core structural walls and perimeter moment frames (i.e., dual wall-frame system). the last 20 years, nearly 800 new have been built in country roughly 70% of them less than ten stories. Although seismic performance these was deemed satisfactory previous earthquakes, their a...

This paper is devoted to probability-statistical analysis of Jackson opened and closed networks. A problem of an estimation of product limit distributions parameters using load coefficients of network nodes is solved. Cooperative effects in aggregated opened and closed networks are investigated and optimization procedures of their limit deterministic characteristics are constructed. Formulas of...

Lysostaphin is under development as a therapy for serious staphylococcal infections. During preclinical development, lysostaphin-resistant Staphylococcus aureus variants have occasionally been reported in vitro and in vivo. The acquisition of resistance to this drug, however, leads to a significant increase in beta-lactam antibiotic susceptibility, rendering methicillin-resistant S. aureus (MRS...

OBJECTIVES Sleep is essential for recovery and performance in elite athletes. While it is generally assumed that exercise benefits sleep, high training load may jeopardize sleep and hence limit adequate recovery. To examine this, the current study assessed objective sleep quantity and sleep stage distributions in elite athletes and calculated their association with perceived training load. DE...

The potential for the development of resistance in oxacillin-resistant Staphylococcus aureus (ORSA) to lysostaphin, a glycylglycine endopeptidase produced by Staphylococcus simulans biovar staphylolyticus, was examined in vitro and in an in vivo model of infection. Following in vitro exposure of ORSA to subinhibitory concentrations of lysostaphin, lysostaphin-resistant mutants were idenitifed a...
